上SVP官方论坛看了眼,果然验证了我的说法
Motion vector grid sets values of three svpflow parameters: block.w, block.h, block.overlap.
The smallest value give more smoothness, more fluidity, but more artifacts.
Advises: Change it to smaller to increase local smoothness. Change it to bigger to decrease artifacts.
Decrease grid step setting manages amount of calls to recalculation function with block size dividing (refine.[thsad1, thsad2, ...]).
Using of it can give more smoothness and decrease waves-artifacts, but makes more visible halo around moved objects.
Advises: Change it to smaller to increase local smoothness. Disable it to decrease halo-effect. |
